WAGON BOLSTER SPRING.

SPECIFICATION forming part of Letters Patent No. 397,832, dated February12, 1889.

Application filed June 15, 1888. Serial No. 277,238. (No model.).

T0 all whom it may concern:

Be it known that I, JAMES CLIFF, of the town of Scriba, in the county ofOswego, in the State of New York, have invented a new 5 and usefulImprovement in \VagomBolster Springs, of which the following, taken inconnection with the accompanying drawings, is a full, clear, and exactdescription.

This improvement relates to the class of vehicle-springs wherein aspring is secured to a spring-hanger attachment mounted on the bolsterof a wagon, forming thereby a springsupport for either the seat or thebody of the wagon; and my present invention consists, essentially,in thecombination with the springhanger attachment, which is mounted on thebolster, of torsion-springs secured at one end to the spring attachmentand the other end to the support for the body or seat of the wagon.

It consists, furthermore, in making the spring attachmentadjustable toadapt it for use on bolsters of different widths, whereby the device maybe imtnufactured of a standard size and readily adjusted, as desired, tomount it on any wagon-bolster varying from the aforesaid standard indimensions.

It also consists in the detail construction and arrangement of theparts, all as hereinafter more particularly described, and pointed outin the claims.

In specifying my invention reference is had to the accompanyingdrawings, forming a part of this specification, in which-like lettersindicating corresponding parts in all the views- Figure 1 is a detachedview of the bolster with my improved bolster-spring and springhangerattachment mounted thereon, illustrating the application of the same toa wagonbolster for use.

Fig. 2 is an enlarged view of mounted on the bolster.

Fig. 4- shows an enlarged sectional view of the modification in theconstruction of the ad justing-jaw for securing the spring-hangerattachment to the bolster, and Fig. 5 is an enlarged detached View ofthe adj Listing-jaw.

A represents a wagon-bolster provided with the standards B B, thebolster A being constructed in the usual manner and of any desireddimensions.

a is a hanger attachment, mounted 011 the bolster and provided with theangular de pending arms a a, which terminate in horizontally-projectingarms b b, as best shown in Fig. 2. One of the arms 6 is provided withthe adjustable jaw e, which fits snugly within one of the vertical armsa of the hanger attachment a, and has its base flanged to guide the jawc rectilinear for the purposes of adj usting the hanger attachment to tothe bolster A.

It will be understood that the jaw 12 is slotted through its base inorder to allow the jaw e to slide on the screw-bolt c to effect thedesired adjustment, and the jaw c is securely retained in place by meansof said screwbolt and the washer 3 and nut d.

The spring-hanger attachment to is mounted transversely over the bolsterA, as best shown in Fig. 1, so that the arms I) I) stand horizontally orlengthwise of the wagon,.and two of the hanger attachments are mountedon each bolster, as best shown in Fig. 1.

z 1. denote torsion-springs, constructed, preferably, of a single pieceof wire or spring metal, as best shown in Fig. 2. One end of the spring15 is provided with the eye t, through which the screw-bolt 0 passes,and the screw-bolt 0 serves to secure the lower end of the spring t tothe spring-hanger attachment. The opposite or upper end of thetorsion-spring tis provided with the eye 25 by means of which it issecured to the angular cross-tie), as best shown in the enlarged view,Fig. 2.

It will be observed that I employ two torsion-springs 25, mounted, inthe manner described, on the arms I) b of the hanger attachment a,opposite each other, so as to support the angular cross-tie f, and atthe same time this arrangement of the torsion-springs t 6 serves toofiset the pressure or tension of the spring and cause the said springsto support the wagon-seat or wagon-bod y equal l y, which resultis accom'ilished by the peculiar action of the torsion-sprin when pressure is apilied thereto. The springs work against each other, and consequentlyexert: a uniiormly-equal pressure or tension, and thereby provide a veryetlicientspring for use on wagon-bolsters.

I11 order to secure the lower ends, 1*, ol' the t0rsion-springs againstturning ortwisting in their seat on the projecting arms I) h, 1 providethe said arms I; with flanges l, as best show-11in Fig. 1, whereby theeve I of the spring is pressed firmly or seated within the recessesformed by the flanges, and thus prevented from turning on its seat. Itis absolutely necessary to secure the l'Ol'SlOll-Sllfllllg 6 fromtiiirning, in order that it may exert its pressure equally, and thisdesired result is socured by the described construction. The springprojects through an opening, 2, in the flanges, as best shown in 5. Theupper ends, of the torsitm-springs are swurcd to the cross-tie f byscrmv-bolts e, as described, and may have some play on the ssrew cwithout effecting their action in use.

The cross tie j" is prmided with angular flanges f, which serve assupports for the seat U or body of the wagon-box. .lt will be observedthat in order to apply my improved spring and its spring-hangerattachment to a wagon-bolster it is simply necessary to place thespring-hanger at'taclnnent a over the holster, as shown in Fig. 2, setby a jaw, 2, so as to clamp the attachment (1. firmly to the bolster A,when the device may be secured by tightening up the nut (I.

At Fig. i I illustrate a modification in the construction of the clamping-jaw,wh ich makes a very efficient device for the desired purpose, andat the same time a very simple one in its construction. I provide theplate 7 with the projection 0, which takes in a block of wood, 5, andcast a projecting lug, 4;, from under the top of the hanger attachment(1, and fit the block of wood 5 on the plate 7 and projection .L andsecure the same to the arm I) by means of the washer 2 and nutd.Itwillbe observed that the block 5 takes the place of the jaw c, andshould be of a suitable size to adjust the hanger attaclnnent u. to thebolster A. The support (1 [or the wagon-seat or wagon-box is usuallynotched to embrace the bolster-standards 1- 13 to guide the springs H intheir up and-down movement.

The operation of my invention will bereadily understood from theforegoing, and the device is exceedingly simple in itseonstruetion,therefore very economical to make, and very etlective in use for thedesired purpose, since it provides a very easy-acting spring, which canbe readily attached to or detached from the bolster ot' lumber-wagons orother heavy vehicles, and thereby transform the same into aspring-vehicle at; a very small expense.

Having thus fully described my invention, whatl claim as new, and desireto secure by Letters Patent, is

l. The emnbination, with the bolster A, of the spring-hanger attachment(1, having the adjustable jaw c, and a spring, I, secured to theattachment u, substantially as and torthe purpose set i'orth. I

2. The combination of thespring-hangeraltachment (,1, having the angulararms a at, projeetimis I) I), provided with :ilanges l, and opening 2 insaid flanges, with the torsionsprings having the eye t, secured betweenthe flanges l and projectingthrough the opening 2, all sul)stantially asand for the purpose set; 'l'orth.

i The cmnbination ol' the spring-hangtmattachmeint u, umunted on thebolster A and provitiled with project-in arms Z), the said arms 1)having flanges I1 and openings 2 for the reception of the eyes t of thetorsimi-springs I, the torsion-springs t having eyes i, bolted to thearms (1, and eyes 1' bolted to the angular cross-tie f, and thecross-tie f, all substantially as and for the purpose set forth.

In testimony whereof I have'hereunto signed my name, in thepresence oftwo attesting wit n esses, at S yracuse, in the coun ty of Onondaga, inthe State of Ne\ .'Yorl(,tliis 22d day of May, l $48K.
